JAMES MOODY, OF HARWICH, MASSACHUSETTS.-

Letters Patent No. 84,567, dated December 1, 1868.

To all whom it may concern Be it known that 1, JAMES MOODY, of Harwieh, in the county of Barnstable, and State of Massachusetts, have invented a new and improved Wagon-Jack; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification. I

Figure 1 is a side-view of iny improved jack, and showing, in red lines, the position of the parts when the lever is lowered.

Figure 2 is a detail sectional view of the same, taken through the line a -:v, fig. 1.

Similar letters of reference indicate corresponding parts.

My invention has for its obj eet to-furnish an improved wagon or lifting-jack, simple in construction, e-fi'e ctive in operation, and not liable to get out of order; and

It consists in the construction of the various parts, as hereinafter more fully described.

A is the standard of the jack, consisting of two parallel bars or plates, a, securely attached, at their lower ends, to the base-block a and placed at a suitable distance apart to receive the other parts of the jack between them.

B are two parallel bars or plates placed within and between the outer bars, a, with which they correspond in shape.

b is an inclined block, having steps or notches formed in its upper side, and which is securely attached to the upper ends of the two bars B, so as to'be raised and lowered with the said bars.

O are two parallel bars or plates, corresponding in shape with the shape of the bars B, between which they are placed. I

D is the operating-lever, which is made in about the shape shown in fig. 1, and which is pivoted to and between the interior parallel bars 0, as shown in fig. 2, and in dotted lines in fig. 1.

E is a pin, passing through holes in the outer parallel bars a, through vertical slots in the intermediate parallel bars B, through curved slots in the interior bars 0, and through a hole in the lever D, as shown in figs. land 2.

F is a pin, passing tln'ough vertical slots in the exteriorparallel bars a, and through holes in the intermediate and interior parallel'bars, B and O, as shown in the drawings. I A

By this construction, as the outer end or handle of the lever 1) is lowered, the intermediate parallel bars B are raised verticallyu'pon the pin E, and carrying the pin F up with-them along the slot .in the outer bars a, while, at thesame time, the interior bars 0 are moved upward and rearward, as their movement is guided by the curved slots in'the upper parts, of said bars 0 moving upon the pin E, so that when the lever D is lowered into the position shown in fig. 1, thejack will be" fully raised and locked.

'In using the jack, it is moved forward under the axle of the carriage or other object to be raised, until the said axle or other object rests upon one or the other of the notches or steps upon the upper side of the inclined block b. The lever D is then lowered, raising .the object away from the ground, and locking the jack in position, so as to .hold the object raised.- When the purpose for which the object was raised has been accomplished, it may be lowered gently to the ground, by simply raising the free end of the lever D.

I claim as new, and desire to secure by Letters Patent-- The wagon-jack, constructed as described, of the base-block a, parallel side bars a, provided with vertical slots, and carryin the notched block b, the inter mediate parallel bars slotted vertically, the interiorparallel bars 0, having the curved slots, the fixed pin E, sliding pin F, and lever D, all operating as described, whereby, as the bars B O and pin F are raised by the depression of the lever, the bars 0 are thrown rearward, locking the lever D in position, for the purpose specified.
